Its my first time and after doing some reading I have somewhat of an idea of what I need to do to reach my goals.

Age:25
Height:5'8"
Weight: 155
BF %: 7-9%

I am a mixed martial arts fighter and need to pack on a bit of size. I want to gain strength and about 20lbs. Im hoping to get there with a 6 or 10 week cycle. I plan on doing The following

wk 1-6: Test (Cypionate or Enanthate )
wk 1-6: Dianabol
PCT
wk 7-12 Nolva

Im not sure about the doses, how long I should take the Nolva, and whether I should add some Anavar or Kynoselen to the PCT. I would much appreciate the advice. Also, should I take some SERM druring the cycle or is it ok to just wait til the PCT?
